# How do I linearize a square root graph?

1. Sep 23, 2014

1. The problem statement, all variables and given/known data
These are the Points.
X values: 0, 1.98, 3.96, 5.94, 7.92, 9.9
Y values: 1.98, 7.13, 9.08, 11.04, 12.57, 14.51
I need to find the original equation and the linear equation. I can't seem to find the line for square root graphs.

2. The attempt at a solution

I know it's a square root graph, but that's about it.

You know or suspect that $y\propto\sqrt{x}$?
Then plot $y^2$ vs $x$.

Another way of getting a straight line is to plot the data using log scales for both variables.
